GREŇOVÁ, Romana
The aim of this thesis was to formulate a questionnaire for respondents who were students of the first and second degrees from randomly selected primary schools in the municipality of Prostějov with extended powers, and thus evaluate the pupils' awareness of treatment with chemicals commonly used in the home. This issue is related mainly to parents of minor children. Most of them do not even know how many hazardous substances are stored at home, and how fatal accidents may be associated with them. Children are often said false information, for example, that drugs are sweeties. Nevertheless it would be sufficient to inform children about danger of chemicals. It is also necessary to think about storage of gasoline or other solution, because pet-bottle of Kofola is not a good choice. The first section of the theoretical part is devoted mainly to compulsory school system and things connected with the study at elementary schools. It describes the Framework educational programme for elementary education, curriculum and its layouts associated (connected) with the issue of human protection in emergencies. Next section focuses on the administrative districts of municipalities with extended powers. It defines basic terms such as administrative district. It describes the administrative district of municipalities with extended powers of Prostejov in detail. Another section is devoted to dangerous chemical substances. It defines basic terms such as toxicology, acute exposure, chronic exposure and more. It describes all the features according to physical security and also features of substances that are dangerous to our health. Thus the reader is aware of what information is on chemicals normally used at home. The following subsections describe dangerous chemicals used in everyday life,especially safe dealing with them. It defines the Toxicology Information Centre. In which cases people call there, what is the telephone number, what to say first and what question they ask. The most important subsection deals with storing chemical substances at home and the first aid in case of poisoning of children by individual funds. In the second part of the thesis the hypothesis of low awareness of chemicals used in households among pupils from schools in the municipality of Prostějov was formulated. The aim of the research part of the thesis was to find out if the awareness of chemicals used in ordinary households among pupils are high or low. The research was conducted at 1st and 2nd grade of primary schools. Pupils fill in the questionnaire with 13 closed questions. From the results we can see, that the awareness of chemicals used in ordinary households among pupils at 1st grade is low. The results were compiled in Excel program and were evaluated in graphs. The statistical analysis of the results was conducted in R program, where all graphic outputs were exported directly from this program and all the values were copied from the output of the program. Kruskal-Wallis test was used at the end of the statistical survey to verify hypotheses. Based on the results, we can confirm the null hypothesis, we can say that both grades have reached the same results in the questionnaire. In conclusion the thesis proposes precautions that could improve the knowledge of pupils of compulsory school attendance in manipulating with dangerous chemicals commonly used at home, and thus to prevent accidents, which continue to rise.
